The Trump administration and its supporters – including the Wall Street Journal editorial page – are working overtime these days to spin the news around the Iran war to make it appear that the US is winning and Tehran had better submit to Washington’s demands before it is wrecked, maybe even “annihilated.” Indeed, Trump is preparing the option of bringing the military hammer down on Iran after the midterm elections if Tehran has not surrendered by then.

In effect, Trump and his supporters are waging a “maximum pressure campaign” against Iran in the mainstream media.

This campaign is sure to fail. If anything, it reflects the Trump administration’s desperation. The president started a war the United States was bound to lose, and there is little he can do now to change that basic fact.

Trump’s propaganda campaign has two dimensions – one economic and the other military.

First, the administration argues that Iran is being economically strangled by the US naval blockade coupled with Operation Economic Outcast, the strategy announced by Treasury Secretary Scott Bessent on 24 August 2026. At the same time, it maintains that oil is once again flowing out of the Gulf at rates not far below those that prevailed on 27 February 2026. The implications are obvious: the economic punishment being inflicted on Iran will force it to capitulate soon, while the US economy – and the international community more generally – is well on its way to recovery.

Second, the US is now building up its military forces for a massive military strike after the mid-term elections, when Trump will be free of electoral constraints. This growing threat of a devastating US attack, coupled with the economic pain being inflicted on Iran, is designed to get Tehran to quit now, before its situation becomes even worse.

There are huge problems with this strategy. It sounds persuasive when the mainstream media dutifully purveys it, but it falls apart when one looks closely at what is actually happening.

Consider the military dimension. The headlines say the US is sending 10,000 additional troops and a third aircraft carrier – the USS Theodore Roosevelt – to the Persian Gulf region, creating the impression that Iran will soon be confronting three American carriers. Moreover, the additional troops – on top of the roughly 50,000 US troops already in the region – are portrayed as evidence that Trump is seriously considering putting boots on the ground.

The aircraft carrier story, however, is quite different from what the headlines suggest. The Roosevelt is reportedly being sent to replace the USS George Washington, while the supposed third carrier, the USS George H.W. Bush, has already left the Middle East and is now in Thailand. Thus, there is presently only one carrier in the region. Indeed, this is the first time during the war that the US has only one carrier in the Middle East, and it is difficult to imagine that there will be more than two – if even that many – after the midterm elections.

The larger problem is that the Iran war is severely straining the US Navy. Its senior leaders warn that the current operational tempo is not sustainable indefinitely. Carriers and other warships are being rotated through extremely long deployments, which cause significant maintenance and readiness problems that will have to be addressed at some point. This problem is compounded by the fact that US ships have lost access to nearby logistics facilities and increasingly depend on a supply chain that reaches back to Diego Garcia, which is about 2,500 miles from the Persian Gulf.

But even if three carriers are available to strike Iran, what could they accomplish in a renewed air campaign that the US and Israel could not accomplish together during the failed 40-day bombing campaign between 28 February and 8 April 2026? Some might argue that the US could finally destroy Iran’s oil infrastructure. The problem, however, is that Iran retains a second-strike capability and could retaliate by wreaking havoc on the oil infrastructure of the GCC states. One shudders to think what the consequences would be for the international economy.

On top of all this, the US faces a serious shortage of high-end weaponry, which is one of the main reasons it ended the 40-day bombing campaign and has shied away in recent weeks from engaging in tit-for-tat bombing exchanges with Iran. One would think that the shortage of critical munitions – both for striking Iran and defending against Iranian retaliation – would limit the scope and intensity of any renewed strategic bombing campaign, thereby reducing its chances of success.

Regarding ground forces, simply counting the number of U.S. military personnel in the Middle East is misleading when assessing the possibility of putting boots on the ground. What matters most in a ground war is the number of troops in actual ground-combat formations. I estimate that, of the roughly 50,000 U.S. military personnel already stationed in the region, about 5,000 belong to such formations: roughly 2,200 Marines and sailors in the 11th MEU, 2,000 soldiers from the 82nd Airborne, and possibly another 800 Army personnel in Kuwait associated with Task Force Spartan. Of the roughly 10,000 additional personnel now being sent to the region, another 2,200 belong to the 13th MEU. Most of the remainder are sailors assigned to the Theodore Roosevelt carrier and its supporting warships. Thus, given present deployment plans, I estimate that by late November the United States will have just under 7,500 personnel in ground-combat formations in the Gulf region—roughly 4,400 in the two MEUs and 2,800 Army personnel.

There is no way a ground force that small provides a promising option against a country with Iran’s population and geography. Even tripling that number to roughly 23,000—which is highly unlikely—would not fundamentally alter the problem. Retired Army General Barry McCaffrey estimates that securing the Strait of Hormuz would require roughly 150,000 troops and three to six months of fighting. For comparison, Russia invaded Ukraine in February 2022 with roughly 190,000 military personnel, and that force proved insufficient to hold much of the territory Russia initially captured. Iran has more than twice the population Ukraine had at the beginning of the Russian invasion, and its geography is considerably more forbidding for an invading army.

Simply put, the United States has not assembled anything remotely resembling the ground force required for a large-scale invasion of Iran. Indeed, from Tehran’s perspective, an American decision to launch such an offensive with anything resembling the forces presently available would present Iran with an opportunity to fight the United States under exceptionally favorable circumstances.

At the risk of beating a dead horse, two further points are in order. First, given how unpopular the Iran war is with the American public, there would almost certainly be a huge uproar if large numbers of US soldiers began coming home in body bags. Second, how are the Marines, who are aboard amphibious assault ships, supposed to land on Iranian territory if the missile and drone threat from Iran is forcing the US Navy to keep those large and vulnerable ships far from the Iranian coast?

Let’s turn to the economic dimension. There is no question that the US is doing great damage to Iran’s economy and inflicting enormous hardship on the Iranian people. But that has been true for a long time. The key question is whether that punishment can coerce Iran into surrendering to American demands.

There is no evidence that Iran is caving in to American pressure, and there are three reasons to doubt that it will. First, it is exceedingly difficult to find a case in the historical record in which an economic blockade by itself caused the target state to surrender. Second, Iran sees the US and Israel as existential threats to Iran – hardly surprising given the genocidal language Trump has used when talking about Iran – and states that believe their survival is at stake are exceptionally difficult to coerce. Third, Iran has a formidable escalation option if the economic pain becomes too great: it can attack the oil and gas infrastructure of the Gulf states and Israel, as well as their highly vulnerable desalination plants.

In short, it is difficult to see economic pressure alone forcing Iran to accept Trump’s terms. That is probably one reason the United States is once again talking about using military force. But, as I argued above, that option holds little promise of producing a favorable outcome.

Finally, there is no question that more oil is flowing out of the Gulf today than was the case in early September. But both Iran and the Houthis are working hard to reverse that trend. Iran is attacking US-escorted tankers on a daily basis, while the Houthis are targeting vital oil infrastructure inside Saudi Arabia. Moreover, despite the increased flow of oil out of the Gulf, gasoline prices remain very high, and a host of other economic problems show no signs of easing anytime soon, including high diesel prices, persistent inflation, elevated mortgage rates, and dangerously high bond yields across much of the West.

All of this is to say that the Trump administration has powerful economic incentives to shut this war down as soon as possible. Indeed, it would hardly be surprising if there were a growing sense of desperation behind closed doors among Trump and his advisers.

This, of course, helps explain why the Trump administration and its allies are waging a media campaign designed to persuade Iran that its days are numbered and that it had better concede to American demands before it is too late. The facts, however, tell a different story. The success of this strategy therefore depends on Trump being able to bamboozle the Iranians into believing that Godzilla is closing in on them. There is little reason to think Tehran will be hoodwinked.
